LOOM.

Specification of Letters Patent.

Patented J an. 22, 1918.

' Application filed June 19, 1917. Serial No. 175,564.

To all whom it may concern:

Be it known that I, FRANK SonwARz, a citizen of the United States,residing at Mc- Cleary, in the county of Grays Haidoor and State oflVashington, have invented certain new and useful Improvements in Looms,of which the following is a specification.

This invention relates to looms and more particularly to portable handlooms and has for its principal object to provide a new and novel typeof foldable and portable hand looms for weaving rugs and the like.Another object of my device is toprovide an improved and novel heddleconstruction which embodies alternate holes and slots. Still anotherobject of my device is to provide a hinged and foldable heddlesupporting standards which may be folded up out of the way when notsupporting the heddle.

Other objects will appear as my invention is more fully explained in thefollowing specification, illustrated in the accompanying drawings andpointed out in the appended claim.

In the drawings Figure 1 is a side elevation of my device with partsbroken away. Fig. 2 is a fragmentary plan of same with parts omitted.Fig. 3 is a front elevation of my improved heddle and heddle supportingframe.

Referring more particularly to the drawings numeral 1 indicates sillswhich are arranged in parallel pairs, are secured together by crosstimbers and are hinged at their adjacent ends to center cross timbers 2.At the outer ends of sills 1 end posts 3 are hinged and are normallyheld in a vertical position by means of removable braces 4. It will benoted that the end posts 3 may fold inwardly fiat against the sills 1.End posts 3 are channeled at their upper ends to provide a notch forsupporting the head blocks 5. Stationary heddle posts 6 are erected onthe cross timbers in line with the sills 1 and are provided at theirupper ends with foldable heddle holders 7 which have heddle retaininggrooves in their upper ends. One of the head blocks 5 is provided with aseries of hooks 8 to which the ends of the warp threads 9 are secured,the other head block 5 is provided with holes through which the warpthreads pass. Pegs 10 are used to contain the warp threads While theypass through head block 5.

After passing through the head block 5 the warp threads again passthrough an inter mediate block 11 and thence to individual spools 12. Myimproved heddle 13 is provided with alternate parallel slots 14 andholes 15. The holes 15 are preferably located midway the length of theslots. Every alternate warp thread passes through one of the slots 14and the other alternate threads pass through the holes 15 so that whenthe heddle is in position every other warp thread is slidable verticallywith respect to the heddle and the remaining warp threads are fixedvertically with respect to the said heddle. In operation the heddleholders are folded down against the standards 6 thereby allowing freemovement of the heddle which is grasped by the operator and is firstdepressed thereby separating the alternate warp threads as shown inFig. 1. When in this position the bobbin containing the woof is passedhorizontally between the depressed and normally positioned warp threads.The heddle is then brought up against the woof in order to drive it backsolidly into the fabric. The heddle is returned to approximate positionand is raised above normal position thereby drawing the alternate warpthreads to a point higher than the normal warp threads and another woofthread is placed in position. It will be understood that the alternatenormal threads are the ones which pass through the slots 14: and whichremain approximately stationary whereas the other warp threads are theones which pass through the holes 15 and which are alternately depressedand raised above the normal threads in order that the alternate warpthreads may cross between each woof thread. For easement oftransportation the end members 3 may be folded down against sills 1 andsills l in turn folded up vertically into position parallel with theposts 7 and the normal position of the heddle thereby forming a smalland compact package.

WVhile I have shown a particular form of embodiment of my invention, Iam aware that many minor changes therein will readily suggest themselvesto others skilled in the art without departing from the spirit and scopeof the invention, and I therefore desire to avoid being limited to theexact form shown and described.

Having described my invention, What I ed intermediate the said endposts, heddle claim as new and desire to protect by Letholders foldablymounted on the upper ends 10 ters Patent, is: of the said heddle posts,and heddle means In the device of-the class described the normallysupported between the said heddle 5 combination of hinged sills, endposts hinged holders.
